摘　　要：试验旨在筛选适宜宁夏引黄灌区种植的丰产优质饲草大豆。试验以17个蔓生型大豆种质为研究对象,通过聚类分析和主成分分析,综合评价其产量和品质性状。结果显示:不同饲草大豆的饲草产量、粗蛋白含量、干物质消化率、干物质采食量和相对饲用价值均存在明显差异。主成分综合评价得分前5位的种质为:FML10>HML0164>JD21>F1918-7>FML2,归于系统聚类中的第Ⅰ类,Ⅰ类种质属于相对丰产、高蛋白、高物质采食量和高相对饲用价值类的饲草。研究表明,FML10、HML0164、JD21、F1918-7、FML2大豆种质更适宜于宁夏引黄灌区作牧草大豆利用。The study was to screen high-yield and high-quality forage soybeans suitable for planting in Ningxia yellow river irrigation area.A total of 17 trailing soybean germplasm were taken as research objects,and their yield and quality traits were comprehensively evaluated by cluster analysis and principal component analysis.The results showed that there were significant differences in forage yield,crude protein content,digestible dry matter,dry matter intake and relative feeding value of different forage soybeans.The top five germplasms scored by principal component comprehensive evaluation were FML10>HML0164>JD21>F1918-7>FML2,belonging to the first category in the systematic cluster.These germplasms belong to the category of relatively high yield,high protein,high material intake and high relative feeding value.The study indicates soybean germplasm FML10,HML0164,JD21,F1918-7 and FML2 are more suitable for pasture soybean utilization in Ningxia yellow irrigation area.
